Troubleshooting when Avast Account returns the 'No data about device available' error in case of the Avast Anti-Theft connection attempt

If Avast Account returns a 'No data about device available' error when you try to send Avast Anti-Theft commands to your mobile device, refer to the troubleshooting instructions in this article. To follow these instructions, you need to have a direct access to your device.

If you are using Avast Anti-Theft as the standalone app, we highly recommend you uninstall it and start using the Anti-Theft feature available in the Avast Mobile Security app. The standalone version of Ant-Theft has been retired and it is no longer supported. However, if you would like to keep using the standalone version anyway and you experience the issue described in this article, refer only to the instruction about clearing Anti-Theft data.

Instructions

Ensure that the internet connection on your device is enabled (via Wi-Fi or by using mobile data).

Ensure that you are logged in to the correct Avast Account on your mobile device (if you have more than one Avast Account):

In Avast Mobile Security, tap the menu icon in the top-left corner and select Avast Account.

Verify if the email address visible on the screen is the same email address as you used to log in to your Avast Account in the browser to locate your device. If it is not, log out from the account you are currently logged in on your device and log in using the correct address.

Disable Anti-Theft and enable it again.

In Avast Mobile Security, tap the menu icon in the top-left corner and select Anti-Theft.

Tap a slider so that it changes from the ON to the OFF position, then tap it again.

Restart your device.

Clear Anti-Theft data:

These steps can differ depending on your Android system version and device model.
